Static Vehicle magnetic field measurements

Background: Magnetometers can be used to measure changes in local magnetic fields caused by the influx of conductors. In this study, a matrix(15x7) of magnetometer sensor data were collected and analyzed. Seven magnetometers were aligned and placed on the pavement, to represent the x-axis, as the vehicle was driven over in 1ft increments, representing the y-axis.

Experimental Setup:

• Seven magnetometer sensors aligned in a one-dimensional x-axis array equally spaced 2ft apart

• 2005 Audi TT Roadster convertible, curb weight 3,384 lbs, footprint dimensions 5’8” Width x 13’3” Length

• Magnetometer readings (z=microgauss) were taken every 1ft (y-axis array) distance for a total matrix of (15x7) measurements

Results:

• The highest peaks represent the engine and front-axle area occupying the highest concentration of metal conductors.
  
• The driver is sitting at the wheel and his magnetic signature can easily be spotted.
